BP Drill Crew Proceeded Against Negative Test

It is always sad when experienced
and well trained men have a lapse in judgment.We will never know what actually contributed to the lapse, but it should
not have been even exhaustion.

There is nothing more critical to
a driller than the certainty of well integrity.This is a mistake that almost could not be made, yet it was made.It is like picking up a gun and not breaking
it open.It is not supposed to happen.

As mentioned here, the blow out
preventer even working would not have prevented the explosion.At least that source can be tossed away
although it certainly shows up a huge problem in training or procedures.Obviously were you find one blind spot, it is
certain that others existed and in this case that big other was apparently well
integrity.

In this case, the test worked and
indicated a problem with well integrity.The workers or whoever proceeded anyway and squeezed the trigger.

(Reuters) - BP had workers on the doomed Deepwater Horizon rig who
could have prevented the missteps that led to the massive Gulf of Mexico oil
spill, but they were not consulted, the White House oil spill commission said
on Thursday.

In an expanded report on the causes of the BP drilling disaster that
killed 11 workers and ravaged the U.S. Gulf coast last summer, the
commission released new details about the events that preceded the BP accident.

The commission's investigators said BP workers failed to ask a
knowledgeable company engineer who was visiting the rig about unexpected
results from a critical negative pressure test on the rig.

"If anyone had consulted him or any other shore-based engineer,
the blowout might never have happened," the commission said in a
statement.

The rig crew's misreading of that pressure test and the decision to
move ahead with temporary abandonment of BP's Macondo well was a major catalyst
for the April 20 rig explosion that eventually unleashed millions of barrels of
oil into the Gulf of Mexico.

Had BP's well site leaders brought their faulty explanation of the test
results to either of the visiting engineers, "events likely would have
turned out differently," the commission report said.

The two engineers who were visiting the rig that day said they would
have insisted on further testing, had they been consulted.

"The sad fact is that this was an entirely preventable
disaster," the commission's chief counsel, Fred Bartlit, said in a
statement. "Poor decisions by management were the real cause."

Created by President Barack Obama during the BP oil spill, the
commission released its major findings and recommendations last month.

The expanded report on the causes of the accident does not change any
of the commission's previous conclusions, but is meant to provide the public
with the "fullest possible account" of the accident, the commission
said.

While the commission does not have the authority to enact policy or
take punitive action, the panel's findings could affect future criminal and
civil cases related to the spill.

Other new details released in the report include the finding that BP
knew that there were issues with Halliburton and its work years before the accident.

The commission previously criticized Halliburton's cement job on the
rig, saying the company may have completed the job before knowing its cement
formula was stable.

The new report said BP's engineers had problems with the Halliburton
engineer assigned to the Macondo well for years, but they still did not review
his work carefully.

In addition, the flow of oil and gas that led to the explosion
"almost certainly" came through an area of the well where
Halliburton's cement should have blocked the flow.

Another key finding was that any flaws in the blowout preventer were
not the root cause of the explosion.

Some Republicans criticized the commission's findings because the panel
never examined the blowout preventer, which they say could have possibly contributed
to the accident.

The rig crew did not activate the blowout preventer until hydrocarbons
had already flowed by it, however, the report said. "Even if the BOP had
functioned flawlessly, the rig would have exploded and 11 men would have
died," the report said.

Transocean Ltd, which owned and operated the Deepwater Horizon rig, was
also accused in the report of missing several signs that hydrocarbons were in
the riser pipe of the rig prior to the blowout.

About Me

18 years old, having cleaned out my HS library, I concluded the only ambition worth having was becoming a great genius. An inner voice cheered. Yet it is my path I have shared much to the Human Gesalt. Mar 2017 - 4.56 Mil Pg Views, March 2013 - Posted my paper introducing CLOUD COSMOLOGY & NEUTRAL NEUTRINO described as the SPACE TIME PENDULUM. Sep 2010 -My essay titled A NEW METRIC WITH APPLICATIONS TO PHYSICS AND SOLVING CERTAIN HIGHER ORDERED DIFFERENTIAL EQUATIONS has been published in Physics Essays(AIP) June 2010 quarterly. 40 years ago I took an honors degree in applied mathematics from the University of Waterloo. My interest was Relativity and my last year there saw me complete a 900 level course under Hanno Rund on his work in Relativity. I continued researching new ideas and knowledge since that time and I have prepared a book for publication titled Paradigms Shift. I maintain my blog as a day book and research tool to retain data, record impressions, interpretations and to introduce new insights to readers.
